Application filed July 28, 1881.

' reciprocating churns; and the object of my improvement is to affordfacilities for the proper adjustment of the dasher to the quantity ofcream desired to be churned, thereby adapting the device to variouswants of different families. I attain these objects by the mechanismillustrated in the accompanying drawings, in which j Figure 1 is a viewin perspective of the machine, with portions of the frame broken away Iand churn attached. Fig. 2 is a view of the fly-wheel inverted,illustrating the cap or slide that secures the crank-pin in place whenad justed. Fig. 3 is a sectional view of the flywheel, illustrating moreclearly the flywheel and pitman-rod and the adjustable pin connectingsaid rod with the fly-wheel.

Similar letters and figures refer to similar parts throughout thedifferent views.

1 1 of Fig. 1 refer to the uprights or cornerposts, 2 2 the side boardsor slats, and 3 3 the cross-ties or girders. These parts constitute theframe-work of the machine. On the top of the frame is journaled thedrivingshaft B, carrying the crank A and pulley D, and forward of saidshaft is another shaft, F, carrying pulley G and fly-wheel H, the twopulleys G and D being connected by a belt, E. Flywheel H is providedwith a series of holes located at different distances from the center,and each hole is of a square or equivalent eontour for nearly itslength, and is then circular. A wrist-pin, O, of a contour to fit anyone of the holes, is inserted from the rear side of the Serial No.139,032. (Model) wheel, and is prevented f om endwise movement by a cap,P, hinged to the wheel and' adapted to cover any one of the holes in theseries. Connected to the front protruding portion of this pin isapitman, l, the upper end of which is inserted in a slot in a pivotedlever, J, and is secured therein by a pin. The pitman is also providedwith a series of holes at its upper end, and when the crank-pin isadjusted as described it can likewise be adjusted. By the meansdescribed the motion of the pivoted lever can be regulated with greatnicety, and the throw of the dasher-rod and dasher K in churn L adjustedto operate on the quantity of cream desired. The churn is secured ontable M by means of movable pins 41 a.

I am aware that the operating devices of my churn are mainly old, andalso that it is common to adjust the throw of a dasher by means of apitman capable of connection with any one of a series of holes in afly-wheel; but I am not aware that the peculiar devices herein describedfor connecting the wrist-pin with the [ly-wh'eel have-been beforedevised.

\Vhat I claim, and desire to secure by Let ters Patent, is-

The combination, with driving devices and the pivoted dasher-operatinglover, of thetlywheel provided with a series of holes each of squarecontour throughout the greater part of its length, the wrist-pin shapedto fit in any one ofsaid holes, the cap pivoted on the rear side of thefly-wheel and adapted to cover any one of the holes in which the pin maybe placed, and the pitman attached to the wristpin and connecting thesame with the pivoted lever, as described.
